Before upgrading, it is recommended to update the installed packages to latest version. Check the current version of your machine.

It is strongly recommended to run upgrade inside GNU screen or tmux to protect the upgrade process in case anything should go wrong with the X session during the upgrade. tmux and screen are available in the main openSUSE repositories.

Here i am using tmux, if you don’t have tmux. Install tmux by using the following command.

server:~ # zypper install tmux

Switch from terminal to tmux.

server:~ # tmux

Enter the following command to start upgrading to openSUSE 13.2.

server:~ # zypper dup

Once the upgrade process is completed, reboot the machine. Check the current OS version.
